The Heritage
The strap for this watch is made to measure
On the Bulgari Octo the bracelet is drawn as part of the case: no catalogue strap will fit. In the atelier we take the measurements on the watch itself and build the strap on the piece — that is the work of Casati Milano.

Can I fit a standard strap to the Bulgari Octo 103431?
No, the bracelet is integrated into the case. The lug system doesn't accept a conventional strap. What I do in the atelier is craft a bespoke strap directly on your watch case, shaping the attachments to respect Genta's octagonal geometry.
How does the bespoke strap process work for the Octo 103431?
We work exclusively at <a href="/pages/casati-booking">Casati Milano</a>, by appointment only. I take measurements directly from your watch case, study the angles, and handcraft the strap piece by piece. Nothing off-the-shelf—everything sewn by hand onto your Octo.
Which leather do you recommend for this watch?
For the Octo I prefer Mississippi alligator with wide scales. It has an architectural presence that speaks to the radical simplicity of the steel case. Alligator ages beautifully, holds its structure, and reinforces that geometric character the Octo demands.
How long does a bespoke strap last?
It depends on wear and care. A well-made strap in quality leather lasts 5–7 years with regular wrist time. The leather evolves, develops patina, darkens. Treat it right—avoid standing water, dry it off—and it will age in a way you'll actually enjoy watching.
Why does the Octo have an integrated bracelet?
Gerald Genta designed it that way for absolute visual continuity. The eight sides of the case flow into the bracelet without interruption. It's not a commercial choice: it's architecture. That's why it demands meticulous study in the atelier when a strap change is needed.
The next step
The right strap isn’t chosen. It is built, together.
From the atelier appointment to delivery, every step is made for those who know that things done well take time. Rare leathers, one piece at a time, eighteen months of warranty.
